| Carbohydrate Name | Lipopolysaccharide (Drugpedia) |
| Carbohydrate Class | Lipopolysaccharide |
| Microbe | Rhizobium leguminosarum (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | LPS is composed of three parts: (1) lipid A, (2) core polysaccharide, and (3) O antigen. The lipid A region contains two glucosamine sugar derivatives, each with three fatty acids and phosphate or pyrophosphate attached. The core polysaccharide has KDO and attached to lipid A. The side chain O is small polysaccharide chain extending outward from the core, it has several peculiar sugars and varies in composition between bacterial strains.

| Proposed functions | LPS is most unusual constituents of outer membrane. It plays important role in host defence avoidance. LPS contributes to the negative charge of the bacterial surface. Lipid A is often toxic and act as endotoxin |
| Antigenic Nature used to produce antibodies | Mixture of suspension of cell envelop. |
